I've been working for something over a year (off and on) on a tunic for Dan for SCA. It's black linen, with hand-embroidered knotwork bands around the neck, the hem and the sleeves. I'm on the last sleeve know. The bands are made up of two knotwork lines, one red outlined in blue, the other gold outlined in dark red, filled with stem-stitch, I have absolutely no idea how much time I've put into it so far. I've almost finished with the first line on the last sleeve. I've got about 3 inches of embroidery to go. And I just noticed that I have filled the blue with gold! Eep!

Dan wants me to just keep going and fill the dark red with red, there's some contrast there but not as much as I'd like--and it would mean that the red and gold are reversed on that sleeve. On the other hand, that's probably 20-30 hours of stitching to rip out. On the other other hand, that 20-30 hours is only a fraction of the total, when you look at the project as a whole.
